Advanced Infrared Driveway Monitor for Superior Security

Introducing the DCMT-4000, a cutting-edge Driveway Alarm Sensor designed by Dakota Alert to provide unparalleled monitoring of your property. This sensor is crafted to detect every vehicle or person that enters your driveway, offering real-time alerts and unmatched peace of mind.

The DCMT-4000 is a Reliable Driveway Alarm Sensor that Detects When Cars Enter Your Property

Dakota Alert’s DCMT-4000 is a driveway alarm sensor with a range of up to 1 mile. When triggered, it will transmit a signal up to one mile away (5,000 ft.) to one of the two compatible 4,000 alert receivers, the DCR-4000 and the RE-4K Plus.

Discover the Power of Passive Infrared Technology

This state-of-the-art sensor is motion-triggered when movement is detected in the monitored zone. Users typically place the sensor on one side of the driveway, where the invisible PIR beam shoots across the driveway to detect cars as they enter. The sensor is outdoor rated.

How the Sensor Works

The DCMT-4000 is a motion sensor/transmitter compatible with the DCR-4000 & the RE-4K Plus Dakota Alert receiver. The sensor shoots out a narrow beam across a driveway. When a car or person passes through the monitored zone, it immediately sends a wireless signal up to 5,000 ft. away to a compatible receiver.

Outdoor Motion Sensor with Customizable Settings

Tailor the DCMT-4000 to your unique needs. Adjust the sensitivity range from 25 ft. to 100 ft., depending on the size of your driveway and your specific requirements. The sensor includes an optional LED indicator, an outdoor filter to minimize false triggers from natural elements and a customizable reset feature to control alert frequency.

Jumper pins inside the transmitter/sensor allow you to change the sensor’s settings according to your needs.

  1.  You can adjust the sensitivity (or range) of the sensor according to your needs. For example, the low setting will create a detection zone up to 25 ft. across, while a high-range setting will create a detection zone of 100 ft. across.
  2. You can turn the LED on or off. When the sensor is transmitting, you can determine whether you want an LED to show.
  3. Filter on or off.  If you are using the sensor outside, it is recommended to turn the filter “on” to filter out triggers from small objects like falling leaves.  Setting the filter to “off” makes it very sensitive and is recommended for indoor use.
  4. Reset changes the time between activation or triggers.  It may be set to reset 10 seconds after the trigger or 120 seconds after the trigger.  If you have a busy driveway or another area you monitor, you may want to use the 120-second trigger so it does not go off as much.

Seamless Integration with Dakota Alert Systems

The DCMT-4000 is a vital component of the Dakota Alert Driveway System. It seamlessly integrates with the DCR-4000 and RE-4K Plus receivers, creating a robust and responsive alert system for your home or business.

Thank you!

This is a purchase I should have made a long time ago. I recently electrically fenced my 1.5 acre property due to deer damage to my fruit trees. The deer then started walking up the driveway! Now I can meet them at the door, as well as delivery folks, friends and family. I can catch the dog if she leaves the property and have peace of mind to have my kids free range. My wife was skeptical, but was won over when we snatched a delivery with the baby napping and not a bark from the dog. Customer service was also quick and helpful when I confused the order. Thank you!

works like a charm

Bought 3 sensors, furthest is 1000 feet out, with some trees in the way. All seem to be going off repeatedly and reliably. Very satisfied, and reasonably priced too
